Some of us here can't stop raving about the ChiaoGoo Red Lace needles. The tips are stainless steel with sharp points and the join to the cable is very smooth. But what sets it apart from other circular needles is the cable. It is a multi-strand steel cable coated with nylon. This makes it firm but flexible and it just won't kink!
The 24" length (from tip to tip) is great for smaller sweaters and scarves.
